SIP trunking services close cost gaps around mobility

As companies begin to heavily rely on mobile networks, calls to and from mobile devices can become a costly issue. With many employees now carrying two or more phones, Session Initiation Protocol (SIP) trunking allows the service provider to send calls out to multiple devices simply by signaling the carrier network to transfer the call, which saves an outbound port.

Most often those evaluating SIP trunking are looking to reduce PSTN access costs. This expert e-guide discusses how and what SIP trunking pros are doing with their network, including:

  • Leveraging SIP to reduce the number of PSTN trunks
  • Over-subscribing IP bandwidth to better size access trunks to corporate needs
  • Reducing the number of trunks required to support fix-mobile convergence
  • And more
